Renewable energy

Renewable energy systems require reliable thermal fluids

Renewable energy systems such as geothermal installations and solar thermal systems rely on heat transfer fluids to efficiently transport thermal energy. Glycol‑based fluids are used to ensure stable performance across varying temperatures and operating conditions. These systems require reliable protection against freezing, corrosion and performance loss, particularly in long-term installations exposed to environmental changes. The required glycol concentration depends on system design and temperature conditions.

Thermal fluids in renewable energy applications

In renewable energy systems, heat transfer fluids are used to transport thermal energy between sources, storage systems and distribution networks. Depending on the application, these fluids may be exposed to high temperatures, sub‑surface conditions or continuous operational cycles.

To ensure efficient operation, heat transfer fluids must deliver predictable thermal performance while providing protection against corrosion, degradation and deposit formation throughout the system.
